Message

The first time a program is run under use Acme::Morse::Audible;, it will become a playable MIDI file with the Morse encoding of the code. (Dots and dashes encoding, actually. Morse Code contains only alphabet.) The program will continue to run as it did before, but will now also be audible. (Some players might not play it unless you rename it to .mid.)

Running the audible program with no Acme::Morse::Audible; instead of use Acme::Morse::Audible; will make it readable back again (and no longer audible). The no Acme::Morse::Audible; has no affect on a readable program.
